This invention relates to the field of standard reference material development and evaluation technology, and discloses a precision-based method for controlling and evaluating the uncertainty of calibration standard reference materials. This method effectively guides the design, control, and evaluation of the uncertainty of calibration standard reference materials, promotes the quality improvement and upgrading of standard reference material development, and provides a scientific basis for users to select suitable calibration materials. This invention uses the inherent precision of the measurement method as the core quantitative basis, constructing a complete technical system of "forward design control at the development end - reverse application evaluation at the user end." By establishing a quantitative constraint relationship between the uncertainty of calibration standard reference materials and the uncertainty of the measurement method, the development of calibration standard reference materials is upgraded from empirical judgment to quantitative science. Simultaneously, it provides users with a quantitative basis for selection and evaluation, achieving a precise match between the uncertainty of calibration standard reference materials and the measurement method.

The utility model belongs to the technical field of automobile body front end manufacturing and assembling, and particularly relates to a wind shield of a heat dissipation module, which comprises an aluminum core body, core body side pipes and wind shields, the left side and the right side of the aluminum core body are fixedly connected with the core body side pipes, and the upper side and the lower side of the aluminum core body are provided with the wind shields sleeved at the pipe ends of the core body side pipes. When the wind shield is used, the wind plate is used as a windward plate for isolating a gap between the wind shield and the aluminum core body instead of increasing the size of the aluminum core body, so that the problem of performance surplus generated when the aluminum core body is heightened is solved, and the manufacturing cost is also reduced.

The application discloses a bimetal saw blade and a preparation method thereof, and belongs to the technical field of special steel production. The preparation method comprises the following steps: smelting, rolling, cold rolling and saw blade manufacturing of the raw materials in a designed proportion. In the process, by controlling the composition of the raw materials, controlling rolling and cooling in the hot rolling process, preparing the structure in the cold rolling process and the heat treatment process in the saw blade manufacturing process, the bimetal saw blade can be obtained under the condition of using only 50-60% of the alloy cost, and the service life of the bimetal saw blade can reach more than 80% of the service life of the X32 high alloy steel. For specific use environment, the performance requirements can be met by using the product, and performance excess can be effectively avoided. In addition, by optimizing the composition, controlling the hot rolling process, the cold rolling process and the heat treatment process, the purpose of achieving a relatively high service life under the condition of low alloy cost is realized without additional processes and equipment, and the raw material cost and the manufacturing cost are effectively reduced.
